Mamaroneck Frostbite Association Rules and Regulations
(Fleet organized and rules originally laid out in 1958.  Revised 2010.  Subject to future amendment by a two thirds vote of full members.)

FOUNDERS: The Mamaroneck Frostbite Association was organized in 1958 by the late Emil Mosbacher Jr, Warner Willcox, and Howard McMichael, to develop the sport of one-design dinghy racing.  Its first season was 1958-9.

MEMBERSHIP: The Association is open to any qualified sailor who wishes to compete and who will abide by these regulations.

RACING SEASON: Fall through Spring.  Typically, the season will include both Saturday and Sunday during November, March and the first half of April and only Sunday the rest of the season.

ANNUAL DUES: The annual dues are based on the anticipated expenses for the current year, i.e. dock fees, crash boat operators, maintenance of committee boat, crash boats, marks, ice breaking, prizes, and miscellaneous expenses.

PRIZES: Prizes shall be awarded in each division at the conclusion of the season's racing and for any regattas held during the season.

SAFETY:  NO MEMBER IS PERMITTED TO SAIL DURING THE SEASON UNLESS A CRASH BOAT IS OPERATING. NO BOAT IS PERMITTED TO LEAVE THE AREA OF THE FLOATS UNLESS A CRASH BOAT IS NEARBY. NO BOAT IS PERMITTED TO LEAVE THE RACING AREA BEFORE THE FINISH OF THE DAY'S RACES.

CAPSIZING:  IT IS MANDATORY THAT ASSISTANCE BE RENDERED IF POSSIBLE. ASSISTING BOATS WILL BE AWARDED POINTS COMMENSURATE WITH THEIR POSITION AT THE TIME THE INCIDENT OCCURRED, OR OTHER EQUITABLE MEASURE AS DETERMINED BY THE RACE COMMITTEE.

SAFETY EQUIPMENT:  A Coast Guard approved Type II or better life preserver or float coat must be worn by all contestants. A paddle and bailer must be aboard. A boat must have enough foam flotation to keep it above water, if it capsizes. A painter of 1/4-inch minimum diameter and an 8-foot minimum length must be attached to the bow of the boat.  The Class recommends that sailors use a floating line for the bow line, that they attach their rudder to the boat with a short line, and that sailors carry a whistle.

BOAT SPECIFICATIONS: Nine-foot Dyers Dhows maintained as originally delivered from stock at the time of manufacture, except for the following:
Screws and rivets may be replaced with bolts.
A fabric dodger may be used to cover the bow.
Painting is permitted, color is optional.
Gunwale guards are allowed.
An additional bracket may be added to each side of the center seat (four brackets total) but the location and length of the center seat must not be changed.
Boat bottoms may be reinforced with fiberglass, but such reinforcement shall come no closer than 3 inches from the chine.
Hiking stick is optional. It shall not extend so that it interferes with the traveler.
Centerboards may be either the standard wood or fiberglass, but their original shape may not be altered in any way.
Centerboard handles may be constructed of any material, but shall be the same length as the original handle.
The centerboard may be attached to the boat with a bolt that passes through both sides of the centerboard trunk.
The sides of the grooved wooden part that is attached to the thwart, and rests upon the centerboard trunk, may be extended vertically.
A mast-step plate may be mounted on the forward thwart, but shall be no thicker than 1/8 inch.  The front end of the mast must be at least 21 inches from the bow of the boat, as measured from the inside of the shell of the boat, just under the bow rail.  The top of the front seat of the boat may be no higher than 13½ inches from the bottom of the boat, as measured at the center of the front of the seat.
Masts: Alspar, Dwyer, and Zephyr aluminum masts, or standard wooden masts may be used.
Headstay may be adjustable.
Booms: Standard Dyer wood, or aluminum booms are allowed.
The outhaul fairlead may have a sheave that turns, and must be located on top of the boom or through the boom vertically. It may not be located on the side of the boom. The outhaul may have a two-to-one mechanical advantage.
Boom vang is optional and may be affixed to the base of the mast and to the boom in front of the forward sheet block. If present, the vang will consist of no more than two parts.
Outhaul cleat must be located forward of front mainsheet block on the underside of boom.
Running rigging may be of any material but the diameters must not be less than 1/4 inch for sheet, halyard, and downhaul, and 3/16 inch for the outhaul.
Wire or rope traveler for mainsheet must raise 11 inches plus or minus 1/2 inch over the transom. A block may be added to the traveler to make a three part mainsheet. The third part must fasten to the boom behind the original aft block.
A sail downhaul adjustment is allowed.  The line may be attached to or pass through the grommet on the tack of the sail for luff tension adjustment.
All types of cleats and blocks are allowed.
The Class strongly recommends that members place a name or their sail number on their transom in letters at least two inches tall.  Members should also mark all of their equipment with their boat name or sail number, including their boom, rudder, and mast.

WEIGHT: A minimum of 200 pounds (crew, ballast, and equipment) is required. Sinkable ballast may not exceed 20 pounds. A contestant found to be below minimum weight shall be disqualified for the day; this disqualification score may not be used for a throw-out day.

REGULAR SAIL AND STORM SAIL: All contestants must use special one-design regular sail and one-design storm sail made for MFA by DOYLE SAILMAKERS. Contestants must use the smaller storm sail, if the race committee posts the storm sail flag.
Sails may not be re-cut or altered. Only one sail may be purchased per year after the first year that a contestant joins the fleet. Conforming Sobstad sails made prior to 1990 will be allowed. Conforming Hild sails will be allowed. The tack of the storm sail may not be raised higher than 31 inches above the heel of the mast and all masts must have a black line indicating this measurement.

MEASURER: The Class Committee shall appoint a Measurer whose duties will be to see that all boats and sails conform to MFA one-design principles, and that the weight minimum regulations are complied with.
